Re: [Xen-users] Urgent: How to evaluate Xen migration performance??

[Siddharth Wagh <siddharth.wagh@xxxxxxxxx>]

It looks like xentop can help me out here.

But when I try it out, it gives me the following error:
OSError: [Errno 2] No such file and directory


Thanks & Regards,

Geez man,

Talk about cutting it a bit close.

You sound like a client who wants the magic "render button" next to the any key.

Take a week and do some research, the traditional Unix tools will give you the info you need.

In my tests, the Xen migration took just a few minutes but this is of course using shared storage of some kind.

Hello all,

I am running Xen 3.0 on two physical machines with Centos 5.2 installations. I need to evaluate the performance of Xen with respect to total migration time, downtime, sizes of VMs, CPU usage and its effect on other applications running on the VMs.

Is there an in-built mechanism to judge these parameters? How do I go about making these measurements?

I have a presentation tomorrow about the same, and would be grateful for any help on the matter.

Thanks & Regards,
Siddharth Wagh
